Title: Improvements in chemically modified elastomers
IPC: C08C19/28
Filed: 1954-02-16
Abstract: Synthetic elastomers are dry mixed with maleic anhydride and the mixture is heated, in the absence of organic peroxide or solvent and in the presence of an inhibitor of free radical polymerization, to at least 150 DEG  C., preferably while mechanically mixing and desirably in the substantial absence of oxygen. Elastomers specified are copolymers of butadiene, isoprene, piperylene and 2,3-dimethylbutadiene, with styrene, methylstyrenes, acrylonitrile, methacrylonitrile, acrylic and methacrylic acids and their alkyl esters, acrylamide, N-substituted acrylamides, vinyl pyridines, fumarate esters, methylene malonic acid esters, vinylidine chloride, methyl vinyl ketone and methyl isopropenyl ketone.  The examples also include a terpolymer of isoprene, butadiene and styrene (11) and mixtures of elastomers (10).  The inhibitors of which many are listed belong to the following classes: phenol derivatives, aromatic amines and their quinonoid derivatives, condensation products of aromatic amines with aldehydes or ketones, organic phosphites and phosphate esters including those specified in U.S.A. Specification 2,587,477. To obtain a product having substantially no cross-linking a mixture of inhibitors, one of which inhibits self cross-linking at 150 DEG C. (e.g. aryl phosphites), is desirably used.  Ingredients which may be included before, during or after the reaction are further inhibitor; softeners such as pine tar, coal tar (Bardol) and petroleum oil; plasticizers such as polyesters (Paraflux), dinitrochlorobenzene and xylyl mercaptans; and inert fillers or pigments such as carbon black, clay, titanium dioxide, lithopone, blanc fixe and diatomaceous earth.  The adducts may be cold milled to reduce their viscosity, they may be blended together and they are of equal or lower viscosity than the original elastomer and are soluble in the same solvents, e.g. benzene and methyl ethyl ketone.  The adducts may be vulcanized with the oxides, hydroxides and carbonates of zinc, magnesium, calcium, barium and divalent lead and are useful as water-resistant coatings or for making composite articles of metal and rubber.

Title: Improvements in or relating to induction motors
Inventor: RAWCLIFFE GORDON HINDLE
IPC: H02K3/28

Abstract: 806,486. Change-pole windings for dynamoelectric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 4, 1957 [Feb. 14, 1956], No. 4617/56. Class 35. A 3: 1 pole-changing winding consists of a three-phase, four-pole delta winding which is opened at one corner and fed in series to provide a single-phase, twelve-pole winding, two other twelve-pole windings being wound in the same stator to give a complete three-phase winding which may be connected in star or delta. As shown in Fig. 1 for a twelve-pole star connection the four-pole delta winding 1, 2 ; 2, 3; and 3, 4 is normally fed at l1, 12, 13, but is opened for twelve-pole operation at switch s1. The additional coils 4, 5 and 4, 6 complete the threephase winding fed, as shown, through terminals L1, L2, L3. The pole-change is thus achieved with only the six terminals 1-6. A similar arrangement is described for the delta connection. It is necessary to use three, or a multiple of three, slots per pole per phase. Preferably three slots per pole-phase are used, the four-pole winding distribution being modified by concentrating half of the conductors in the central slot and a quarter each in the outer slots to provide space for the additional twelve-pole windings in these slots. This arrangement has the additional advantage of reducing the 7th harmonic at the four-pole connection. Preferably, the four-pole conductors in the outer slots are slightly reduced in gauge so that they occupy less than half of the slot, the greater part, e.g. two-thirds, being taken by the additional twelve-pole windings which may have a reduced number of turns. The outer slots may alternatively be deeper to hold the two windings without reducing the gauge of wire. Preferably, the twelve-pole winding is at the top of the slots. Saturation of the core may be employed at the higher speed. By reversing alternate coil groups in the four-pole winding connection, the machine may be made to run at two-pole speed. For this purpose, as shown in Fig. 7, the coils 1, 2 ; 2, 3 and 3, 4 are centre-tapped and supplied at terminals 7, 9, 11 to produce a parallelstar connection. It is described how, in addition, the winding may be connected to give a six-pole parallel-star arrangement in which the supply is connected to terminals 7, 12, 13. Specification 797,290 is referred to.

The hooks engage stamped sheet metal eyes attached to the inner sides of the openable parts. A cam 18 on the shaft 9 partially raises the cover 5 as the hooks are withdrawn. To prevent rattling &c., the shafts 9, 11 are mounted in rubber bushes 16 and an anchored spring engages the pin of the pin-and-slot connection.

Title: Apparatus for the transmission of a service channel in a radio link
IPC: H04B17/00
Filed: 1966-02-04
Abstract: 1,129,792. Radio signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Feb., 1966 [9 Feb., 1965], No. 4970/66. Heading H4L. At a repeater in a radio link transmitting a carrier wave frequency-modulated by a baseband signal and a continuity pilot signal lying above the baseband signal, service channel intelligence is inserted on to the pilot signal by means of a phase modulator in the I.F. signal path through which the received F.M. signal passes. As shown in Fig. 2, the incoming signal is frequency-changed at 2a, 2b and supplied via I.F. amplifiers 2c, 3a, phase-modulator 3b and frequency-changer 3e, 3d, to amplifier 3f for re-transmission. The I.F. signal is also fed to a demodulator 5 and the subcarrier pilot signal selected at 6 and fed to the service channel demodulator 7. It is assumed that when a service channel is to be inserted at the repeater the incoming pilot signal is not modulated. Filter 6 supplies the pilot subcarrier via a phase shifter 8 to a ring modulator 9 where it is amplitude modulated with the local service channel signal, the suppressed carrier output of modulator 9 being supplied to phase-modulator 3b. The phase-modulator, Fig. 1, comprises an allpass network L1, L2, C1, C2, C3, varactor diodes D1, D2, D3, being connected in parallel with capacitor C1, C2, C3 respectively. The allpass filter is tuned to pass the I.F. signal but the characteristics of the varactors are varied by the signal from modulator 9 so that the network is wobbled correspondingly in its centre frequency position. By this means the phase modulator 3b introduces components which are equivalent to sidebands of the continuity pilot signal modulated with the service intelligence. If the phase shifter 8 is set to give no phase shift the sidebands added will be representative of amplitude modulation but if it is set to give a 90-degree phase shift the resultant signal will be equivalent to angle modulating the pilot signal.

The drive means may be an electric motor 3, such as are otherwise used for cooling disc brakes, and the several wheels of an undercarriage may have separate motors. The disengaging means may be a free-wheel drive 5, or a clutch controlled by speed sensing means such as a tachometer or a photoelectric device. The system may be such that the drive is disengaged at any speed when a brake is applied; alternatively the brake may be released as the drive is engaged when the wheel speed falls.

Abstract: 967,197. Raising liquids. J. ESTEVE, and H. TRIBALLAT. Feb. 13, 1961, No. 5197/61. Heading F1R. A bulk liquid vehichle transporter for milk comprises a tank fixed to the chassis of the vehicle, in which tank there is a partial vacuum sufficient to draw liquid from a vat fixed to the vehicle on a lower level than the tank and the vat has a mixing paddle and means for sampling the liquid therein. A motor driven pump J provides the vacuum in the tank A and in a sampling device N. A moisture trap G prevents condensation entering the pump and a switch R allows a sample of the milk to be drawn off into the container of the sampling device N. When the vacuum in the tank A is at the correct level a ball valve in the vat is opened to allow the liquid to flow therefrom. An electrically operated valve V controls the system automatically by connecting the pump to a pipe F4 when the vacuum in the tank A reaches its maximum level. A system of lights (Fig. 7, not shown) indicates the state of the vacuum. If the milk churns are too heavy to be loaded directly on the vat for emptying, a suction assembly 29 may be connected to the churn. The assembly 29 has provision for restricting the liquid flow as the churn empties to prevent large quantities of air entering the tank A. When a control handle 30 is unscrewed, air enters the tank A to facilitate emptying through a tap A3, which is opened by the handle 30.
